/**
 *  核心原理
 *  1）、EnableRedisHttpSession导入RedisHttpSessionConfiguration配置
 *      1、给容器中添加了一个组件
 *          SessionRepository=>>>RedisOperationsSessionRepository ==> redis操作session。session的增删改查封装类
 *      2、SessionRepositoryFilter==》Filter: session存储过滤器;每个请求过来都必须经过filter
 *          1、创建的时候，就自动从容器中获取到了SessionRepository;
 *          2、原生的request,response都被包装。SessionRepositoryRequestWrapper, SessionRepositoryResponseWrapper
 *          3、以后获取session. request.getSession();
 *          4、wrappedRequest. getSession(); ===> SessionRepository 中获取到的。
 *
 *      装饰着模式；
 *
 *      自动延期：redis中的数据也是有过期时间
